4 Claims. (Cl. IDS-17) This invention relates to shingles, and more particularly to roofing and siding shingles made of sheet metal, such as aluminum.

Among the several objects of the invention may be noted the provision of an improved construction for sheet metal shingles, more particularly aluminum shingles, which is such that the shingles are economical to manufacture and easy to install in weather-tight and vibrationproof manner, and which are adapted for effective drainage of any condensate that may form on their undersides; and the provision of shingles of the class described which, in addition to having the stated features, may be made to have an appearance simulating that of standard composition shingles. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

Fig. 11 is a section taken on line 11-11 of Fig. 8.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawlngs.

Referring to the drawings, Fig. 1 shows a blank 1 of sheet metal, such as aluminum, shaped for processing into a shingle of this invention. As illustrated, the blank is generally of long narrow rectangular shape. The upper left corner as viewed in Fig. 1 is cut off at an angle as indicated at 3. The lower right corner of the blank is shown to be notched as indicated at 5. The lower left corner is shown as cut off at an angle as indicated at 7. The upper margin of the blank is shown as having a vertical slit 9 adjacent the right end of the blank and a nail hole 11 between this slit and the right end of the blank. The right end margin of the blank is shown as having a notch 13 adjacent the upper edge of the blank. Adjacent its upper edge, the blank has a series of indentations or bosses 15.

Fig. 2 illustrates the outside or weather face 17 of a shingle S formed from the blank 1, and Fig. 3 illustrates the inside or under surface 19 of the shingle. As shown,

ice.

2 the shingle has a first integral hook member 21 on the outside along its top. This is formed by bending over the upper marginal portion of the blank 1 extending from angled corner 3 to the right end of the blank generally on the line 23 indicated in Fig. 1 to overlie the outside face 17 of the shingle. The portion of the hook member 21 to the right of the slit 9 is designated 25 and includes the nail hole 11. The hook member 21 is substantially fiat and extends from the bend on line 23 (which constitutes the upper edge of the finished shingle) at an acute angle to the body portion 27 of the shingle (see Fig. 8). The previously mentioned indentations or bosses 15 are formed in the blank between line 23 and the upper edge of the blank projecting in such direction that, when hook member 21 is bent over, they project inwardly from the hook member toward the face 17 of the shingle (see Fig. 8). In production, the hook member 21 is bent over to the point where the noses of the indentations engage the face 17 of the shingle. However, when the bending force is released, hook member 21 springs back to some extent so that the noses of the indentations are slightly spaced from the face 17 of the shingle. It is preferred that this spacing be less than the thickness of the shingle material.

The shingle S has a second integral hook member generally designated 29 on the inside along its bottom or butt. This is formed by bending over the lower marginal portion of the blank 1 extending from the angled corner 7 to the corner notch 5 to overlie the inside face 19 of the shingle. This bend is preferably made on two lines 31 and 33 so that the hook member 29 has a relatively broad base portion 35 generally at right angles to the body of the shingle and an upwardly extending fiat portion 37 which is spaced from and generally parallel to the body portion 27 of the shingle (see Fig. 8). The base portion 35 forms the bottom or butt of the shingle. The height of the upstanding portion 37 of the 'hook member 29 as measured from its upper edge 3? to its base portion 35 (indicated at H in Fig. 8) is preferably slightly less than the distance measured along the body portion of the shingle from the upper edge 23 of the shingle to the level of the lower edge 41 of the first hook member 21. The spacing of the upstanding portion 37 of the hook member 29 from the body portion 27 of the shingle is preferably slightly greater than the spacing of the lower edge 41 of the hook member 21 from the body portion of the shingle.

The shingle has a third integral hook member 43 (see Figs. 2, 5, 7 and 9) on the outside along its right end edge. This is formed by bending over the end marginal portion of the blank extending between the notches 5 and 13 on the line 45 indicated in Fig. l to overlie the outside face 17 of the shingle. The bend on line 45 constitutes the right end edge of the shingle. The portion of the blank above the notch 13 is not bent over, and forms a nailing tab portion 47 in association with and underlying the portion 25, and projecting endwise from the shingle at its upper right corner.

The shingle has a fourth integral hook member 49 (see Figs. 3, 5, 6 and 9) on the inside along its other end edge. This is formed by bending over the end marginal portion of the blank 1 extending between the angled corners 7 and 3 on the line 51 indicated in Fig. l to overlie the inside face 19 of the shingle. The bend on line 51 constitutes the left end edge of the shingle. Hook member 49 is narrower than hook member 43.

The shingles S are applied to a roof as illustrated in Fig. 5 in horizontal courses with the shingles of any given course horizontally staggered with respect to the shingles of the course below and the course above. The I 43 at the right end of the shingle which lies to the left of the given shingle in the respective course of shingles (see Figs. 5 and 9). The given shingle is set so as to be substantially horizontally aligned with the shingle toward its left and to have its butt hook member 29 (which is on the inside) hooked under the upper hook member 21 of the two shingles in the next lower course (see Figs. 5 and 8). Each shingle, as laid, is fastened by inserting a nail N in its nail hole 11 and driving the nail through the tab portion 47, the tab portion 25 being flattened out on portion 47 (see Figs. 5 and 10).

Since the noses of the indentations 15 are spaced from the face 17 of the shingle less than the thickness of the material, the insertion of the upstanding portion 37 of the hook member 29 of a shingle under the hook me ber 21 of a shingle in the next course below results in outward movement of the hook member 21 against its inherent spring bias and clamping of the portion 37 between the noses of the indentations and the face 17 of the shingle. This prevents vibration of the shingles and makes a tight seal over a broad area to prevent rain from driving between face 17 and portion 37.

Condensate forming on the underside of any given shingle runs down the underside of the shingle and past the edge 41 of the hook member 21 of a shingle in the next course below into the gutter defined by the bend 33 of the hook member of the given shingle. It will be observed that the stamping of the indentations 15 results in drawing inward of edge portions of the metal adjacent the indentations to form depressions 53 in the edge 41 of the hook member 21. These depressions provide spaces insuring flow of condensate past the edge 41 of the hook member, even though the edge 41 may be otherwise in contact with the shingle above. The condensate collecting in the gutter corner at 33 runs down toward one end of the hook member 29 and drains out onto the weather face of a shingle in the next course below.

The shingles may be made from corrugated or embossed sheet aluminum to simulate composition shingles, if desired. For example, the shingles may be made of sheet aluminum embossed to have a grained appearance as indicated at 55 in Fig. 5.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
